I seen a special on the discovery channel, I think it was the discovery channel?????? Anyway, doesn't matter where!! The show was on the Parana. They told how they would form "Packs" and in these "Packs" they were able to eat other fish and animals many times their size. Just saying!!! If your guppies start gaining weight and your tilapia start disappearing????

I mean if they start coming up missing for some reason other than you sqwuushing them with the net!!!!

Hey, I am just trying to cover all the possibilities here, that's all!!
